Cement Kilns: Size Reduction and Grinding

The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage. In the case of raw materials, attempts have always been made to minimise the amount of crushing needed by extracting the rock in the finest possible state.
